What is a sanitary survey of a water system necessary for?

A sanitary survey of a water system is crucial for determining the safety and adequacy of the water supply. This comprehensive evaluation involves identifying potential sources of contamination, assessing the infrastructure, and ensuring that the water meets health and safety standards. By conducting a sanitary survey, public health officials can identify weaknesses in the water system that could lead to pollution or unsafe drinking water conditions, allowing for timely interventions to protect public health.

While analysis of chemical composition and assessment of aesthetic qualities can be important aspects of water quality monitoring, they are typically not the primary focus of a sanitary survey. Similarly, increasing the temperature of water does not relate to the survey's objectives, which are fundamentally centered around safety and adequacy issues.
